1.You and a friend are raising a beam, but your friend's rope is too short and you lift him off the ground. At the current time, everything is in static equilibrium. The unknown tension in your cord is T y, the mass of the uniform beam is known as m, the mass of your friend is known as m,, and the length of the beam is known as L, and the distance along the beam where your friend's rope is attached is known as d. The angles shown in the picture are also known. friend you pin a. Draw an extended FBD for the beam. b. Where should you choose a point of rotation to make it possible to solve for the magnitude of the tension force in your cord? c. Determine ¿T V i in terms of known variables. d. Determine the contact force of the ground on the beam, in terms of known variables. Since you determined i T o V ¿ in the previous step, it is now a "known variable". Hint: you might want to use yb Newton's 2nd Law for translation.
